i can see your concerns in working at the treatment center. maybe putting together a pro/con list would help you make a decision.

one thing to consider is, if you work there, then you can take all the material you witness in your work there and apply it to yourself. talk to some of the staff on the sly with questions you have concerning your personal issues once you have befriended them. if you work there for a long time, you could really benefit from hearing the same information over and over again. going there for treatment you will only hear it once.
